Product Description:
The PSI62C0.775-W1 is a medium-frequency inverter manufactured by Bosch Rexroth Indramat for the PSI Frequency Inverters series. It converts three-phase factory power into a regulated medium-frequency output that drives induction coils, resonant generators, or similar loads in automated production lines. The unit also contains an internal 24 V auxiliary supply, allowing external logic modules, sensors, or contactors to receive power directly from the same assembly. This arrangement reduces the amount of separate power-distribution wiring required inside an industrial control cabinet.
The inverter accepts a mains input of 400–480 VAC at 50 or 60 Hz. Thermal energy is removed through a water-cooled heat sink, and the cooling circuit must carry away up to 420 W of losses during continuous operation. The electronic enclosure has an IP20 protection rating, providing protection against accidental contact with live internal components when the unit is installed inside a control cabinet. An integrated power supply produces a stabilized 24 VDC rail that can deliver up to 2 A for field devices or drive relays. A dedicated Ethernet timer interface supports synchronization with higher-level controllers, allowing frequency ramps and dwell times to be transmitted over standard network wiring.
The inverter weighs 25 kg, allowing it to be mounted on a suitable cabinet panel without specialized structural reinforcement. It can operate at ambient temperatures from +10 to +55 °C, while permitted storage and transportation temperatures range from −25 °C to +70 °C. Its operating conditions meet 3K3 under EN 60721-3-3 for use in clean industrial locations with controlled exposure to humidity, vibration, and airborne contaminants. Proper water flow is necessary to remove heat from the power electronics during sustained operation. Adequate cabinet airflow also helps prevent heat from accumulating around the enclosure and its electrical connections. When these installation conditions are maintained, semiconductor junction temperatures remain within their permissible limits during rated operation.
